## Abstract

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A318-100, A319-100, A320- 200, A321-100, and A321-200 series airplanes; and Model A320-111 airplanes. That AD currently requires modification of the electrical bonding of all structures and systems installed inside the center fuel tank. This new AD requires modification of additional bonding points inside the center fuel tank. This AD results from a report that additional bonding points need to be modified in order to prevent electrical arcing in the center fuel tank. We are issuing this AD to prevent electrical arcing in the center fuel tank due to inadequate bonding, which could result in an explosion of the center fuel tank and consequent loss of the airplane.
